Critical raw materials

Last updated

Governments designate critical raw materials (CRM) (also referred to as critical materials or critical minerals) as critical for their economies so there is no single list of such raw materials as the list varies from country to country as does the definition of critical. [1] They include technology-critical elements, rare-earth elements and strategic materials.

History and background

Analyzing the historical development of country approaches to critical materials, David Peck discusses the interplay between those that emphasize economic growth ("tech will fix it") and those that argue that finite resources will be exhausted ("limits to growth"). These two approaches are a feature of debate around critical materials and both are important, while countries also act in self-interest as well as responding to geopolitical tensions. [2]

Terminology and Country Definitions

For advanced industrial economies the commonly used terms "critical minerals" or "critical raw materials" refer to materials required for their strategic industries where there is a risk of interruption to supply. [3] The Minerals Security Partnership (MSP) is a transnational association whose members seek to secure a stable supply of raw materials for their economies. [4] On 5 April 2024, MSP partners launched the Minerals Security Partnership Forum to enhance cooperation in respect of CRM critical to "green and digital transitions". [5]

US

2023 Final Critical Materials List includes critical materials for energy (sometimes known as the "electric 18") [lower-alpha 1] together with 50 critical minerals. [lower-alpha 2] [6]

EU

The Critical Raw Materials Act came into effect on 23 May 2024. It specifies a list of 34 CRM, including 17 raw materials [lower-alpha 3] considered strategic. [7] [8]

UK

The Critical Minerals Strategy, Resilience for the Future [9] was published in July 2022, updated [10] in March 2023. [11] As of December 2023, the UK does not produce any of the 18 identified highly critical CRM [lower-alpha 4] [12] while a watchlist of increasingly critical materials includes Iridium, Manganese, Nickel, Phosphates and Ruthenium. [13]

China

On November 30, 2023, the Ministry of National Security of China defined critical minerals [lower-alpha 5] as "those irreplaceable metal elements and mineral deposits used in advanced industries, such as new materials, new energy, next-generation information technology, artificial intelligence, biotechnology, edge-cutting equipment manufacturing, national defense, and military sectors." [14]

Criticality

According to the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF), criticality has no agreed definition, varies with time, and is specific to country and context. [15]

Geopolitical risk

There is an increased focus on supply chains in general and for critical materials specifically, highlighted by US-China competition. China is the biggest producer of 30 of the US 50 critical minerals as well as being a significant player in downstream processing and manufacture. [16]

A 2024 analysis from the World Economic Forum states that potential scarcity of critical materials arising from the Energy transition will be driven by demand factors and suggests ways for governments to address the uncertainties involved. [17] [18]

Stable nuclides are nuclides that are not radioactive and so do not spontaneously undergo radioactive decay. When such nuclides are referred to in relation to specific elements, they are usually termed stable isotopes.

A period 4 element is one of the chemical elements in the fourth row of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the same vertical columns. The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block in the table.

A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past and today.

A trioxide is a compound with three oxygen atoms. For metals with the M2O3 formula there are several common structures. Al2O3, Cr2O3, Fe2O3, and V2O3 adopt the corundum structure. Many rare earth oxides adopt the "A-type rare earth structure" which is hexagonal. Several others plus indium oxide adopt the "C-type rare earth structure", also called "bixbyite", which is cubic and related to the fluorite structure.

The galvanic series determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in nobility, and the relative areas of the anode and cathode exposed to the electrolyte. The difference can be measured as a difference in voltage potential: the less noble metal is the one with a lower electrode potential than the nobler one, and will function as the anode within the electrolyte device functioning as described above. Galvanic reaction is the principle upon which batteries are based.

A diffusion barrier is a thin layer of metal usually placed between two other metals. It is done to act as a barrier to protect either one of the metals from corrupting the other.

In metallurgy, non-ferrous metals are metals or alloys that do not contain iron in appreciable amounts.

<span class="mw-page-title-main">A15 phases</span>

The A15 phases (also known as β-W or Cr3Si structure types) are series of intermetallic compounds with the chemical formula A3B (where A is a transition metal and B can be any element) and a specific structure. The A15 phase is also one of the members in the Frank–Kasper phases family. Many of these compounds have superconductivity at around 20 K (−253 °C; −424 °F), which is comparatively high, and remain superconductive in magnetic fields of tens of teslas (hundreds of kilogauss). This kind of superconductivity (Type-II superconductivity) is an important area of study as it has several practical applications.

A native metal is any metal that is found pure in its metallic form in nature. Metals that can be found as native deposits singly or in alloys include antimony, arsenic, bismuth, cadmium, chromium, cobalt, indium, iron, manganese, molybdenum, nickel, niobium, rhenium, tantalum, tellurium, tin, titanium, tungsten, vanadium, and zinc, as well as the gold group and the platinum group. Among the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, silver-mercury amalgam, and gold-mercury amalgam.

The coinage metals comprise those metallic chemical elements and alloys which have been used to mint coins. Historically, most coinage metals are from the three nonradioactive members of group 11 of the periodic table: copper, silver and gold. Copper is usually augmented with tin or other metals to form bronze. Gold, silver and bronze or copper were the principal coinage metals of the ancient world, the medieval period and into the late modern period when the diversity of coinage metals increased. Coins are often made from more than one metal, either using alloys, coatings (cladding/plating) or bimetallic configurations. While coins are primarily made from metal, some non-metallic materials have also been used.

Minor metals is a widely used term in the metal industry that generally refers to metals which are a by-product of smelting a base metal. Minor metals do not have a real exchange, and are not traded on the London Metal Exchange (LME).
